Strategic testing

Add tests only when they protect meaningful behavior or a stable contract that existing checks could realistically miss.

  • Prioritize domain invariants, important edge cases, public interfaces, persisted data, security boundaries, and integration seams.
  • Skip tests for mechanical edits, implementation details, existing coverage, or changes already verified by types, linting, or schema validation.
  • Choose the smallest test level that protects the behavior.

Before adding a test, identify the realistic failure it prevents and confirm that the maintenance cost is justified. If that case is weak, do not add one.
